rss block issue since upgrade

[rbh]

i have a couple center blocks set up as rss blocks. the feeds come from topix.net, and before the upgrade all the links were bold with the short story description normal text. since the upgrade the links are now the same font as the story description and also there is a big orange topix.net banner showing up. i dont care if this is forced down from topix.net and it can stay but it wasnt showing till i did the upgrade. could it be that topix.net changed thier feeds at the exact time i upgraded the tp? what file might i have made edits to in .86?
